Doctors grumble at the popularity of alternative medicine, but the truth is that we still have a monopoly. This is not so in other civilized nations. In France and Germany, for example, herbal medicine is mainstream - i.e. health insurance pays for it.
When Americans get sick, almost all head straight for a medical doctor. From a doctor’s view, that’s the right decision. Scientific medicine works. But that’s not the reason. The idea that scientific explanations are the best has always been a minority view, and recent nutty events haven’t changed matters. In a free election, ghosts would win and evolution lose -- by a landslide.
Americans mostly prefer medical doctors just as we prefer baseball and big cars. It’s an American thing. We don’t eat horse meat because…well, we don’t.
